Abstract

In a method of determining the effectiveness of a sterilization procedure using a biological indicator, the biological indicator comprises a holographic sensor and spores or an enzyme. The method and the biological indicator rely on the holographic sensor to indicate the effectiveness of me sterilisation procedure and do not require a conventional pH indicator, a fluorophore or chromophore.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to a method of determining the effectiveness of a sterilisation procedure using a biological indicator and to a biological indicator for use in such a method.BACKGROUND TO THE INVENTION

[0002] Biological indicators are used in the infection control industry to monitor the effectiveness of sterilization procedures using liquid, steam or gas plasma sterilants. The biological indicators are included with every load of articles to be sterilized and act as quality control devices to confirm the antimicrobial effectiveness of the sterilization procedure.

[0003] Biological indicators can be grouped into conventional biological indicators, rapid readout biological indicators and dual rapid readout biological indicators. With each of these types, the failure of a sterilization procedure is indicated by a detectable change in the biological specimen which is either an enzyme, a microorganism, or both.

[0004] Traditional biological indicators...
